  • Publication number: 20080092384
    Abstract: An apparatus and method for installing an intermediate bearing by press fitting the intermediate bearing between a center hub of a crankshaft and a center web of a crankcase and an apparatus that provides support for an intermediate bearing that is installed within the crankcase and coupled to the center web.

  • Patent number: 7329105
    Abstract: A multi-directional pump is disclosed generally comprising a housing with inlet and outlet ports, a pumping device disposed therein, a first chamber in fluid communication with the inlet port, and a second chamber in fluid communication with the first chamber. The first and second chambers are both in direct fluid communication with the outlet port, such that a double pumping effect is achieved while some of the fluid is compressed in multiple stages. In certain embodiments, one or more sealing mechanisms can be activated when particular conditions are desired in order to seal the first conduit by which the first and second fluid chambers communicate, or by which the second fluid chamber communicates with the inlet port, such that a standard double or single pumping effect is achieved.

  • Patent number: 7249556
    Abstract: A compressor is disclosed generally comprising a cylinder head mounted to a cylinder block having a cooling chamber and a piston channel via a bolt. A piston is disposed in the piston channel and has a contact portion that contacts the channel wall, which is integrally formed with the cylinder block, as it slides within the channel. The bolt and the cooling chamber each extend from at least as high as the highest contact point between the contact portion of the piston and the channel wall to at least as low as the lowest contact point between the contact portion of the piston and the channel wall. In certain embodiments, the cooling chamber is located between the bolt and the piston channel. In some embodiments, a crankcase is integrally formed with the cylinder block.

  • Publication number: 20020127116
    Abstract: An axial piston compressor produces air supplied to an air system of a vehicle, typically a heavy duty truck through a plurality of pistons held within a stationary block, and the movement of the pistons is predicated through the control of a pivotal swash plate. The pistons are idle in a neutral position of the swash plate, wherein a pressure above the pistons in the cylinder block counterbalances a thrust generated by an actuator upon the plate positioned in a plane extending perpendicular to a drive shaft. The plate oscillates in response to a pressure drop above the pistons causing the actuator to expand toward the plate and exert a thrust exceeding the lowered pressure above the pistons and enabling the swash plate to provide the pistons with reciprocal motion.
